I have the second beep coming up and after unlocking and starting I get the alarm not available message. Bonnet error is showing when bonnet is open, so I guess that microswitch is OK.
Got a quick diagnostic on my mechanic's OBD station and I got a CANBUS sensor 3 error.
Which lists a crapload of things to check because they are on the same line.
Initial impression is the internal pressure sensor, but I don't think I have one, since I don't have a deactivation button on the top ceiling controls. I guess I shouldn't have an anti lifting sensor as well.
Didn't have much time to go looking for all those things listed though. I must get him to clear his schedule for a whole day so he can track it down.
